What are my options

[Twostroke]

Had my con rod bearing sieze up on me today, not wrist pin but con rod bearing. 05 800 factory mod motor.

Need to get this thing back on the snow asap, leaving for BC next friday (28th) and don't want to ride a borrowed sled.

Doubt anyone near me can press a crank apart and back together in that time but MAYBE. Thinking of just putting a whole new crank and slp tough boy bearings in it, so the whole bottom end is fresh. Top end looks great.

Polaris wants $1000 for a crank?!

What to do?

I know IndyDan has great cranks but don't think I can afford one right now.

I've heard very good things about jjmachinery. I bet if you call them you could work something where while you send yours in, they will send a rebuilt to you but thats their deal, if you have a wide bearing ALREADY installed i believe they can do that too. If you don't have one installed you would need the cases machined to fit it which be a longer turn around unless JJ already has some in stock. Check them out. Hope that help, hella lot cheaper than OEM polaris parts.

I have about 1000miles on my JJ machinery crank that I bought off ebay. Last I checked (200 miles ago or so) the runout was only 0.0015". Seems to be holding up great on my 04' 800. And yes they shipped me the rebuilt crank once I sent them a tracking number for my core crank.

As for the machining the cases for a wide bearing, isn't it simply to open up the oil passage? I did that on mine anyway (but just used a hand drill) as the PTO bearing blocks over half the oil passage in its stock form.

I opted to just use a stock crank (no wide bearing) and made damn sure my cases gave the crank bearings proper bearing crush when torqued down (using a dry crank bearing, checked each bearing journal). Then simply warm your sled up before hammering it.

if and when I rebuild it i'm going to use JJ, seems to be the best deal and they have a good rep. Thanks guys.

Another thumbs up for JJmachinery. They have done several cranks for me. Quick turn around, great prices, and havent had an issue yet with any of their work.
